There are real concerns, though, that Internet porn will increase sex crimes because of the way it portrays things like that.

Anybody can do a simple thought experiment [to refute that]. In the late '60s and early '70s, feminists were saying that porn trained guys to be rapists. That was before home video, and there were probably only 100 different porn magazines in the country. You had to go to [sleazy places to watch porn]. Now there are a million websites where you can get it for free around the clock.

You would expect rape to skyrocket. There are more guys watching more porn more often. But, in fact, rape has gone down in America. Also, in Japan in the mid-'90s, they loosened their obscenity laws. Now rape is down there too. It certainly seems to be case that more access to porn is associated with less rape. Rather than making people want to go out and rape, it satisfies the urge.
